The present invention provides curable compositions comprising non-Sn organo-metal catalysts that accelerate the condensation curing of moisture curable silicones/non-silicones. In particular, the present invention provides Mn(III) complexes that are particularly suitable as replacements for organotin for sealant and RTV formulations. The Mn(III) complexes are comparable or superior to organotin such as DBTDL, superior to Mn(II) compounds, and exhibit certain behavior in the presence of components that allow for tuning or adjusting the cure characteristics of the present compositions and provide good adhesion and storage stability.

Moisture curable organopolysiloxane composition

Disclosed herein are novel copolycarbonates containing repeating units A and B respectively of the formulae: (A) &#x2014;[ROC(&#x2550;O)O]&#x2014;, and (B) &#x2014;[(RO)n-C(&#x2550;O)&#x2014;O]&#x2014;, wherein the molar ratio of units (A) to units (B) is in the range of from about 9:1 to about 1:9, and wherein Ris a divalent C8 to C12 alicyclic group, and Ris ethylene or propylene, and n is an integer ranging from 4 to 40. Also disclosed are silicone hardcoat compositions containing the copolycarbonates and their derivatives. Upon cure, these silicone hardcoat compositions exhibit improved flexibility as compared to that of the conventional hardcoats while at the same time maintain the abrasion resistance of conventional silicone hardcoats.
